I watched this show with my hubby. When the character we hated the most was dying, we both cried. Yes, that's what this show did to us. Captivating!
The way it portrays family relationships is moving, but careful, this is not a romance - at least not in the way one might expect it to be at the beginning. If you aren't interested in history and politics, this show might not be that interesting to you, because it shows lots of real events, including political struggle, travel, and war.
Acting is top notch, costumes and interior design is beautiful (I am not a specialist, so I don't know it this is historically accurate), fictional story is smartly intertwined into the texture of real events. If anyone can recommend more series like this to me, I would be grateful.
